This paper presents the energy and exergy analysis of thermal power plant Tuzla in Tuzla, Bosnia Herzegovina. The main aim this is to analyze components a 200 MW steam unit order identify quantify sites with highest losses calculate efficiency values all when operating at nominal load. influence change ambient temperature block load on value was taken into analysis. further includes impact oper...

This paper discusses coordinated reactive power voltage (Q-V) control in a multi machine steam power plant. The drawbacks of manual Q-V control are briefly listed, and the design requirements for coordinated Q-V controller are specified. Theoretical background and mathematical model of the new controller are presented next followed by validation of developed Matlab/Simulink model through compar...

The thermal-power-plant condenser tubes, conducting cooling seawater, experienced frequent leakages, prompting the hereby presented failure analysis. Visual inspection of corroded/ruptured tube segments revealed that localized corrosion may be linked to seawater sediments and thick layers products at water side. Sediments were found along bottom adjacent point contact between baffle plates exte...

In this paper, an innovative power plant, constituted by a gas turbine in combined-cycle fuelled by a synthesis gas (or syngas), produced in a local biomass gasifier, is analyzed. The plant is integrated with an external combustion system, fed by cellulosic biomass, connected to a heat exchanger able to increase the air temperature, as in a regenerative cycle. The combustion products pass throu...

A comparative analysis of the methods approximate thermal calculation superheated steam condenser compression heat pump supply system is presented. The working substance and condensing refrigerant R410a. When single-zone method applied, calculated by one area with inclusion overheating in condensation use coefficient. two-zone assumes two separate areas, viz. cooling its actual condensation. ap...

Organic Rankine Cycle (ORC) systems are capable of utilising low-enthalpy geothermal sources. The aim of the Above Ground Geothermal and Allied Technologies (AGGAT) research programme is the development of ORC systems within New Zealand. An experimental scale ORC system, known as ORC-B, was built at the University of Canterbury to assist with the research and development of the system design an...

Combined heat and power (CHP) plants have received a resurgence of attention from power system planners and policy makers in an effort to fully realize the potential of the technology. CHP plants that are thermal-primary, however, do not always maximize the benefits provided to the power system. In this study, we examine how power system planning metrics can be applied to CHP plants to better u...

In the present paper. a mathematical model of a combustion steam generator is presented. The model of power plant was implemented using GE GateCycle code. The effects of Over Fire Air and Reburning combustion techniques on the plant performance were studied using from both theoretical and experimental approach. Experimental data were studied and represented depending on the combustion parameter...
